Severe cases of morning sickness may be associated with conditions that are not related to pregnancy.

Pregnancy Complications

Complications can fall into the category that is harmful to the baby and/or harmful to the mother. Many women develop gestational diabetes, which only affects the mother. Preeclampsia, which elevates the blood pressure of the mother during pregnancy, can be harmful to both mother and baby. Ectopic pregnancies can put both the mother and baby at risk when the embryo attaches to the fallopian tube, instead of moving to the uterus. Miscarriages or premature births can also happen to pregnant women with certain risk factors. When going through labor, progress can slow, causing distress for the baby and mother. In some cases, a C-section is needed to keep from causing harm to both the baby and mother.
